To all whmn it may concern:

Be it known that I, TALBOT O. DEXTER, a citizen of the United States, and a resident of Pearl River, in the county of Rockiand, in the State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following; taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to mechanisms employed for alining or registering paper to its requisite position for being folded orotherwise operated upon; and the invention has more particular reference to the class of paper-registering devices in which a pin or point is made to enter into a slit or other perfcration made in the paper'for that purpose; and the invention consists in a novel organization of mechanisms which effect the registering of the paper in an acc'urate'and reliable manner, as hereinafter fully explained.

In the accompanying drawings, Figure 1 is a side elevation of that part of a paper-folding machine to which myinvention is applied. Fig. 2 is a plan view of the front portion of said machine. Figs. 3, 4, and 5are enlarged vertical longitudinal sections on the line X X in Fig. 2, showing the paper-registering instrument in its different operative positions. Fig. 6 is a side View of a paper-folding machine provided with means for relieving the paper from the propelling force of the conveying-tapes I while the registering instruments perform their function. Figs. 7 and 8 are respectively longitudinal and transverse sections of my preferred formof the paper-supporting bars over which the registering-points are placed to open the slits in the paper and to enter into said slits. Fig. 9 is a transverse section on line YYin Fig. 3. Fig. 10il1ustrates a modification of the means for holding the gripper normally in its open position, and Fig. 11 is a plan View of the end portion of the machine which is provided'with lihQVGl': tically-mov'able paper-conveying tapes.

. Similar letters of reference indicate corre- "sponding parts. 7

A represents the main supporting-framed: a paper-folding machine, which frame may be of any suitable shape.

. B B denotes the paper-folding rollers,

which are geared together to cause them to other in the'usual and well-known manner. 0 represents the blade, which tucks the sheet into the bite of said rollers. p

a a are traveling endless tapes which carry the paper into the machine and deliver it front stop or gage, which arrests the movesheet-arresting position for the pu rpose hereinafter explained. For imparting said movement to the front stop various mechanisms may be employed. 1 have preferred to show my Letters Fatentfio. '561-,937,-dated' 5 one 9,

inal' bars I), supported at their inner or rear ends on rollers c and havingfastened to are.pivotally connected to the lower ends of rock-shaft d, which extends across the "maerected on the sides of the main frame A, said rock-shaft receiving motion from a lever e, attached to one'end of said shaft and hearing with its free end on a rotary cam F, which imparts. oscillatory motion to said lever and intermittent reciprocating motion to the bars I) b. The front stop-or gage D rides on .the said bars and is connccted thereto, 'so as to cause it to move with the same bymeans of screws f, passing through nuts f,,afiixed to the said front stopv and journaled in the brackets c, hereinbefore mentioned. These brackets are formed with posts 0 in which is journaled a horizontal shaft 8 extending worm-gears f which mesh with similar gears f attached to the screws f. .B-y turning said and move the "front" stop D backward-or forto alternately advance-to and recede from its sheet-arresting position. Tofront stop I attach two grippers disposed at. opposite ment of the incoming sheet; This front stop. alternately advances to and recedes from its' said mechanisms of the form illustrated in '1 1896.; and it consists, essentially, of longitudiarms (1, suspended from and fastened toa i rotate with their top portions toward each over the folding-rollers, and'D represents the I their outer or front ends brackets c, which chine and is mounted in bearings on pcstse,

across themachine and having fastened to it shaft 6 the-two screws ff are caused to turn ward, as maybe required, for operating on T sheets ofdiiferent lengths. Theafores'aid connection of the front stop D to the longitudinally-movable bars I) 12 causes said :front stop IOO' sides of and equidistant from the longitudinal central line of the machine. The purpose of these grippers is to engage the arrested sheet and impart to it a secondary advance movement simultaneously with the receding movement of the front stop. Each of these grippers I prefer to form of agripper-shoe g, fastened to the base of the front stop D and projecting rearward therefrom to receive upon it the front portion of the arrested sheet, as more clearly shown in Figs. 3, 4, and 5 of the drawings Over each of said gripper-shoes is a gripper-finger g, pivoted to the front stop and having affixed to its pivoted end an arm h, which extends upward and rearward over the gripper finger for the purposehereinafter explained. Said gripper-fingeris to be held normally in its raised or open position either by a weight 2', adj ustably connected to an arm 11, extending forward from the pivoted end of the gripper-finger, as shown in Figs. 3, 4:, and 5 of the drawings, or by means ofa suitable spring j, attached at one end to the front stop 'D and having its free end pressing the arm It of the gripper-finger forward, as illustrated in Fig. 10 ot' the drawings. A setscrewj maybe connected to the front stop directly over the gripper-finger g to limit the upward movement of said finger. Directly over each of said grippers is a vertically-movable arm 70, which in its downward'movement bears on the free end of the arm h, and thereby depresses the gripper-fingerg and imparts the required grippingforce upon the subjacent gripper-shoe g. To permit this gripping force to be regulated so as to allow the gripped paper to be withdrawn therefrom without opening the gripper, as hereinafter described, a suitable adjustable tappetl is interposed between the two arms 7: and 7b, which tappet may consist of a set-screw connected to the arm h of the gripper-finger, as shown.

Various means may be employed to impart the vertical movement to the arm 7;, and I therefore do not wish to be limited in this respect. The means illustrated in the annexed drawings are of the form shown in my Letters Patent No. 561,937, hereinbefore mentioned, in which the arm 7: is fastened at one end to a rock-shaft 7t, receivingmotion from a lever L, attached to the end of said shaft and hearing on a rotary cam L, which, in connection with a spring L imparts an oscillatory motion to said lever.

At the rear end of each of the described grippers is a registering-finger m carried on the arm 7i and extending rearward and downward therefrom and formed at its free end with a registering-point 11., adapted to enter intoa slit made in the paper for that purpose. The registering-finger is supported longitudinally adjustable on the arm L by means of a shoe m, formed on said finger and fitted by a dovetail joint to the said arm, as shown in Fig. 9 of the drawings. A nut '12., projecting from the side of said shoe, embraces a screw n which is journaled in an ear 0, projecting from the arm. Immediately in front of the registering-point n is a shoulder or abutment o, projecting upward from the finger m.

In connection with the described registering-finger I employ under said finger a papersupporting bar 19, which has a portion of its top deviated from the plane of the main portion of the harand in a position to receive over it the slitted portion of the paper. Said deviation may consist either of a bridge 1;, rising from the bar 19, similar to that shown in my aforesaid Letters Patent, or of a longitudinal groove 19 in the top of said bar, as represented in Figs. 7 and 8 of the drawings.

In the operation of the machine the registering of the paper is effected in the following manner, to wit: The paper is carried into the machine by the tapes era in the usual manner. During the delivery of the paper the arms kare in their elevated position to allow the paper to pass under the registering-points n and the front stop D is'in its rearmostposition to arrest the movement of the paper., Said positions of the arms and front stop cause the grippers to be in their normal position. Then the free ends of the arms 7tdescend and cause the registeringpoints a n to depress the portions of the paper at the aforesaid deviations of the planes of the paper-supporting bars 19, and thereby strain said portions of the paper sufficiently to open the slits in the paper. Simultaneously with said opening of the slits the arms is k depress the gripper-arms h h, and thereby close the gripper-fingers 9 upon the paper lying upon the gripper-shoes g. The front stop D then moves forward, and by means of the grippers it draws along with it the paper. In this secondary forward movement of the paper the registering-points n n are caused to enter into the slits in the paper, and the rear edges of the slits are brought in contact with the abutments c on the registeringfingers. These abutments constitute a secondary sheet-arresting gage which prevents further advance movement of the paper and causes the paper to be withdrawn from the closed grippersduring the further movement of the front stops. This withdrawal of the paper from the closed grippers without tearing the slitted portions of the sheet requires very accurate adjustment of the gripping force of the grippers, and for thispurpose I employ .the hereinbefore-described adjustable tappet or set-screw Z, preferably in connection with an adjustable spring-plate n, which is placed lengthwise on the under side of the arm K and is fastened at one end thereto. An adj usting-screw vis connected to the free portion of said spring-plate and is brought to bear on the arm K by the presjusted to apply the desired pressure to the gripper. The aforesaid abutment of tli'ereg The arms is k then rise sufficiently to lift the paper from the bridges p or relieve the paper from depression'into the grooves p in the papersupporting bars 19, and thus obviate tearing or injuring the paper during the operation of introducingit between the folding-rollers B B.

Inorder to guard against buckling the paper by its contact withthe front stop I) and also obviate disturbing the paper from its registered position, I employ suitable means for relieving the paper from the frictional hold of the traveling tapes aa as soon as the paper has come in contact with the aforesaid front stop. For this purpose I prefer to place directly under the tapes aa rollers 'r' r',mounted on shafts r 4", which extend across the machine and pass with their ends through vertical guides it and are connected to the upper ends of toggle-levers, which are pivoted at their lower ends to bearings s s on the frame A, as shown in Fig.6 of the drawings. There is a set of such toggles on each side of the machine to support the ends of the shafts rr.

which receives intermittentreciprocating motion from a rotary cam R; The action of the toggles is timed to lower the roller-shafts'r'r, .soasto causethe paper to ride on the usual stationary bars a, arranged between the tapes, and thus relieve the paper fromcontact with the tapes as soon as the paper has been carried into contact with the front stop and while the blade '0 introduces the paper between thefolding-rollers B B. I dd not limit my invention to theuse of a registering pin or' point entering into the slit in the paper, as this is not absolutely necessary in every instance. The essential feature of said pin or pointis its abutting against the edge of the slit, and thereby arresting the movement of the paper in its registered position. The functions of the pointsn arechiefly to depress the paper, andthereby open the slit'in the-paper, and subsequently lift' the paper to allow it to freely pass into the bite of the folding-rollers.
